The Accentra AU 4708LN Classroom Lockset (formerly Yale) is a high-intent security solution specifically engineered for the rigorous demands of educational facilities, healthcare institutions, and public buildings. As a premier Series 4700LN Grade 1 cylindrical lock, this hardware is designed to prioritize occupant safety while maintaining strict access control. The Classroom Function (ANSI F84) is the gold standard for school security, ensuring the outside lever can be locked or unlocked by key, while the interior lever remains active at all times for immediate emergency egress.
Featuring the modern and ergonomic AU (Augusta) lever design, this lockset incorporates a Free Wheeling vandal-resistant mechanism. When locked, the exterior handle rotates freely, absorbing excessive force and protecting the internal chassis from damage—making it one of the most durable and reliable locks available on the market today.
Industrial-Grade Performance & Safety
- Certified Grade 1 Durability: ANSI/BHMA A156.2, Series 4000, Grade 1 certified. Tested to exceed over one million cycles, providing maximum structural integrity for the highest-traffic environments.
- Classroom Security (ANSI F84): Key-controlled access from the exterior ensures only authorized personnel can enter, while the "Always Active" interior lever prevents accidental lock-ins and meets critical fire-life safety codes.
- Vandal-Resistant Free Wheeling: The exterior handle moves independently when locked, neutralizing attempts to force the lock through excessive torque or physical abuse.
- 3-Hour Fire Rating: UL-cUL listed for all fire doors with a rating up to 3 hours, ensuring full compliance with stringent building and safety regulations.
- Superior Finish & Ergonomics: The straight-return Augusta (AU) lever is ADA compliant and offers a professional aesthetic that fits seamlessly into any modern architectural project.
